[R] update.packages fails on pdf write - CSAgent

[Tim Howard]

All,
I work in a building where our computers are running Windows XP with
Cisco Security Agent (CSA) activated, locking many automated actions,
especially file writes. We (lowly staff) are allowed to install
software, so on upgrading to R 3.0.2, I tried the standard approach for
updating my packages: Copying the non-base folders from my older
installation into the library folder and running
 
update.packages(checkBuilt=TRUE, ask=FALSE)
 
R merrily downloads from the mirror and then continues installation --
until it gets to a package that has a pdf to write, as follows:
 
> update.packages(checkBuilt=TRUE, ask=FALSE)
--- Please select a CRAN mirror for use in this session ---

Here's the message from the Application log in my Event Viewer:
 
The process 'C:\Program Files\R\R-3.0.2\bin\i386\Rgui.exe' (as user
<myusername>) attempted to access 'C:\Program
Files\R\R-3.0.2\library\file8ec2cd16e8\colorspace\doc\hcl-colors.pdf'.
The attempted access was a write (operation = OPEN/CREATE). The
operation was denied.
 
So it seems to me that CSA is blocking the installation of this package
because of the PDF write attempt. Please correct me if my interpretation
is wrong!
 
I can re-install these packages manually, but would love to do it
automatically.
 
My Questions:
 
It seems that the pdf is 'extra' since it isn't required for all
packages. Is there a way for me to tell update.packages to not install
these extras? I don't see that as an option at ?update.packages, but I
may be missing it.
 
Alternatively, is there an easy way to identify and download the zips
needed in a folder of my choice and but then finish the install
manually?
